Last night I went out with prnracing in his s10 RCLB 4.3l 2wd free mods drag radials and ls1edit. We came across a guy in Colorado CCSB 2wd with a drop in K/N filter. Sense we had the traction advantage we could get him out the hole and get him buy a length but as soon as prn truck would go it to 3rd hear come the Colorado and would end up a half to a full length in front of us. It was fun they raced several times. prnracing got him a couple times but in general the Colorado would win. I keeped giving prn a hard time about getting beat by 5cyl told him that his truck is a turd and he needs to get a Colorado.

 

Didnt he have a big nitrous kit on there? My brother had a '00 blazer with a 4.3 in it. What a piece! Isnt the LT1 swap relatively easy on those? Help the guy out!

 

ive seen some pretty quick 4.3's.. But he had the bottle on it.

 

no bottle on it yet but on the high way was the most fun to race

 

my buddy had a blazer 2wd with the 4.3 and he ran a 16.4 at the track. that was when i was running a 15.7. when we would go out on the street, he would be right next to me till like 60. i dont think that is that bad. i heard they make big torque at like 2300rpms?

 

that must have been pretty exciting racing some 18 second trucks

 

ahaha 18 seconds your *** the rcsb colorado runs 15.5 to low 15's good luck raceing one with alittle nos later.

 

ya i was gonna get a rcsb colorado before i ended up finding my truck, those 5cyc have 220hp and they only weigh about 3000lbs

 

I've seen some pretty quick scsb 4.3 s10s around here. One guy had a 5-speed with a couple of bolt-ons,chip and gears (I think 3.73s) and claimed he could out-run an modded ext. cab 5.3. I didn't believe him until I seen him do it. The 5.3 had an intake, muffler and a tb spacer. He killed the ext. cab 5.3 out of the hole and kept pulling on him the whole time. Everybody looked in his engine bay and he had no nitrous.

 

My 4.3l 01' truck went 13.29 on the bottle and 14.9 on the motor. My winter beater should go 13.9-14.2 with a cam and stock vortec heads. So some of them go. the winter beater is a 94' with vortec heads edelbrock intake with the stock throttlebody and programming. Not to mention some trans work.
